I'm not sure that a comparison with a CRT is particularly useful. CRT's are designed to run at a number of refresh rates, but LCD's are usually designed to run at one rate - usually 60Hz in fact. Obviously, according to the manual, Matt's can run at (at least) 60 or 75 Hz. These refresh rates usually are probed by X on startup. Some monitors respond properly, some don't. The tendency is for X to run at the highest allowable resolution and refresh rate, as thats usually what the viewer wants - the higher rate the less flicker etc. If you want something that isn't what X chooses, you are probably best to disable edid detection (thats the probing mechanism) and specify a modeline. There are numerous modeline generators available, online or to run locally. To disable edid I believe the incantation is: Option "IgnoreEDID" "true" Not sure whether it goes in the "Monitor" section or the "Device" section.. -- Nick Rout
